dorayakii, and to ALL
The fact that Time or a state factor collapse has to be "observed" to be said to exist does not necessarily mean that it must be observed by a conscious being. In my opinion, another particle is more than enough to be the "observer" if the particles have an interaction with one another that is able to be ultimately observed.
This is quite right in most parts. I do agree. But we have to assume, that particles must show a certain minimal-configuration to be able to serve as "observer". I do not believe that an elementary particle like a photon is sufficiently complex to sense TIME. A complete atom certainly --> yes, maybe baryons (protons, neutrons), because they are more complex and consist of sub-particles. Note: Every sensed time interval (elapse time) has to be measured and STORED in the particle for a moment. (The shortest time interval possible ist the Planck time 5.39121 × 10 -44 s, as you know). Otherwise no "recognition" or "sensing process" is possible; and if not possible, then there - on the other hand - NO TIME exist !!
But note: You cannot imagine the impact to epistemology and philosophy, if the so-called "physical realism" has to acknowledge, that Kurt Goedel had right, that TIME is indeed only a physical illusion, objectively not existing, and have to be SENSED through a suitable SENSORIUM btw. an "observer" (which can also be material structure, and not necessarily an entity having consciousness e.g. a person).
Such a "physical revolution" will result into a super-paradigma.
